What is the manufacturing process for glass disc insulators?

The manufacturing process of glass disc insulators at Huayao involves several precise stages to ensure durability and performance. First, raw materials such as silica, soda ash, and limestone are meticulously blended and melted at approximately 1400°C. The molten glass is then shaped into discs through a pressing method, ensuring uniformity and strength. Each disc undergoes rigorous annealing to relieve internal stresses.

Huayao emphasizes quality control, conducting electrical tests on each insulator to meet industry standards. The test conditions typically involve dielectric strength measurements under a standard service voltage range. For comparative analysis, you can refer to Sediver, another key player in the industry, for additional specifications. Huayao's insulators usually showcase mechanical strength of 70-120 kN, suitable for various high-voltage applications, thus ensuring reliability.
